Re: My test for SlowChess Blitz Classic 2.4 x64

Thanks for testing, tough second half for SlowChess. This is the first time I've seen someone use the own book in a match. I should start updating it again, I stopped around 1.8. I used to run 2min+1s matches with release candidates, and have it learn the first 13 moves of winning/drawing side(s). ...

Re: Chess engines that are tuned/trained to chess960

I've shared my datasets with a handful of people (most of the guys using OpenBench). Engines like Weiss, which do not know how to play FRC, are actually trained on FRC data as well with gains.

Re: Dragon by Komodo Chess

<snip>We trained partly on 960 games, so this is not just a fluke. It's just a gut feel, but I suspect this may be the secret sauce needed to create a super-aggressive evaluation function. --- Steve So I tried to keep the lid on this after having talked to Mark and finding out that we arrived at th...

Re: TucaNNo: neural network research

Nice! I was thinking that a smaller NN probably won't be able to replace HCE completely, however one might try to build a smaller "correction" network. I'm not sure if it'd work, but the basic idea is to use a hybrid: HCE plus a smaller NN to correct its mistakes. There's still valuable stuff in HC...

Re: My test for SlowChess Blitz Classic 2.4 x64

Good thing I dropped 12.75 with big elo gains.
Don't want Slowchess catching up to Ethereal so quickly, where would the fun be for Jonathan? :)

Re: 2020 NNUE & New Engines Swiss Champs

Might want to work on the formatting of these posts; I have no clue what I'm looking at, so I just looked away. I'm sure others do the same.

Re: Why is the MIT License unpopular in chess programming?

Historically, I cannot say the answer. However, going forward, there is great motivation to use something like the GPL. In a more naive time, one could assume that others would not steal your work and pass it off as your own. Now, that is more true than ever. Fire and Houdini, but many more, and eve...

Re: Mayhem NNUE - New NN engine

Halogen is using a shallow (relative to the KP networks used in computer Shogi) MLP using KP input trained on (AFAIK) Ethereal generated training data using optimized training code written by Andrew. So, Halogen is not using "KP", aka a mapping of King-Piece's in its network, nor is it using the "H...

Instead of copying and pasting somebody else's NNUE code, how about implementing the NNUE algorithm yourself, like what the Komodo, Halogen, and Seer authors did?
Halogen is not using NNUE.
We do not know how Komodo was trained.
I don't know about Seer.
